A few months ago I wondered how the hell people get through certain spots in Jackal, it just seems impossible. The trick is.. the game is actually made for a rotary-type joystick, and the non-rotary/"joystick" versions of game were most likely an afterthought by Konami to sell more boards to operators who didn't want to shell out for the rotary sticks. While I was away for the past 2 days I realized I had forgotten to add the new rotary code to Jackal. Oops. The game is really quite playable and fun now; as it should be.
best regards,
